Question 10: In computer architecture, which cache mapping technique allows a memory block to be placed in any cache line, improving hit rate at the cost of higher implementation complexity?

Correct Answer: Fully associative

Incorrect Answers: Direct-mapped, 2-way set-associative, Victim cache

Explanation: A fully associative cache permits any memory block to be stored in any cache line, increasing flexibility but requiring expensive tag comparisons. A direct-mapped cache restricts each block to a single line, while set-associative caches allow placement within a limited set of lines. A victim cache is an auxiliary buffer, not a primary mapping method.
